A 3-Subset Meet-in-theMiddle Attack: Cryptanalysis of the Lightweight Block Cipher KTANTAN

A number of new cipher designs have been proposed recently, targeting use cases with severe implementation constraints imposed. Block cipher design methods have advanced to a stage where strong arguments for the resistance of the design against large classes of attacks such as differential and linear cryptanalysis are possible. However, if aggressive design decisions have been made forced by a restrictive application scenario, some other, more dedicated analysis techniques may turn out useful for attacking the cipher.
